Google’s mobile OS Android continues to power ahead as the world’s most popular smartphone platform, according to figures out today from Kantar Worldpanel Comtech, the WPP-owned market research company that tracks sales of handsets across key markets on a 12-week rolling cycle. In the nine markets surveyed by Kantar — Australia, China, France, Germany, Italy, Japan, Spain, UK and the U.S., all detailed in the table below — Android on average accounted for 64.2% of all handset sales in the 12 weeks that ended March 31.

The only market where Android did not dominate was Japan, where Apple’s iOS just about eked out a lead against it (49.2% versus 45.8% of sales) for the three months ending March 31. Elsewhere, the figures indicate that regardless of whether the market is developed (U.S., UK, Germany) or emerging (China) or struggling financially (Spain), collectively, Android handset makers are winning them all, with sales figures for the platform reaching their high point in Spain, at 93.5% of all smartphone sales.

As you can see below, when it comes to smartphone penetration of actual devices in use, Android is leading everywhere.
